Abstract: A velvet ribbon with double-sided nap is produced by weaving three superimposed webs (8, 10, 12) connected to each other by nap threads (14). The nap threads (14) of the above triple web are separated between the middle web (8) and a first web (10) in a first cutting device (36, 36a). In a second cutting device (46, 46a) the nap threads between the middle web (8) and the second web (12) are separated to give the middle web as a double-sided velvet ribbon (8). The corresponding ribbon weaving machine (2) comprises three superimposed weaving points (31) each with a weft introduction body and a common shedding device (16). A first cutting device (36) for cutting the nap threads (14a) between the middle web (8) and a first web (12) and a second cutting device (46) for cutting the nap threads (14b) between the middle web (8) and the second web (10) are provided afterwards. The velvet ribbon (8) produced thus has a nap (56, 58) on both sides.

Abstract: A pile fabric includes woven together inner and outer layers and cut pile yarns woven into the inner layer. The outer layer has a higher yarn count than the inner layer, without counting the pile yarns. The pile fabric is one of two substantially similar pile fabrics formed by simultaneously weaving two fabrics that are connected to one another by the pile yarns, and then cutting the pile yarns to separate the pile fabrics from one another. Nonpile surfaces of each of the connected fabrics include an oblique, woven fabric pattern. The fabric pattern of a first of the connected fabrics is at least substantially like the fabric pattern of the second of connected fabrics, except that the fabric pattern of the first connected fabric is not parallel to the fabric pattern of the second connected fabric.

Abstract: A process for the production of a face-to-face carpet fabric on a double pile loom having at least two filling insertion planes, uses filling yarns, stuffer warp yarns, and chain warp yarns to form two back cloths. The filling yarns are inserted into each back cloth as back fillings and inner fillings. Groups of chain warp yarns, individual yarns of which between their respective last binding to an inner filling and the succeeding last binding to a back filling form a holding length, are assigned to each back cloth. All patterning pile loops are stretched over back fillings. and the pattern repeat of a group of chain warp yarns is selected to be greater than six. The holding lengths of a chain warp yarn extend over at least three filling insertion cycles.

Abstract: In face-to-face weaving pile fabrics with high pile density, groups of three weft yarns (1-3), (4-6) are inwoven in respective openings between binding warp yarns (7), (8), (9) (10) crossing each other, and non-pile-forming pile warp yarns are inwoven, while pile warp yarns are alternately interlaced in the top and the bottom backing fabric over a weft yarn according to a two-shot weave. In series of four successive weft insertion cycles in each case three weft yarns (1), (2), (3) are inserted for the top backing fabric (30) and three weft yarns (4), (5), (6) for the bottom backing fabric (31). A weaving machine inserts two weft yarns one above the other per weft insertion cycle and by weft disengagement or weft cancellation in the course of two cycles per series inserts only one weft yarn. Two pile-forming pile warp yarns after a pile change are interlaced over a weft yarn.

These tuft-forming weft filaments are laced into the warp filaments.

Abstract: A method is provided for weaving a false boucle fabric with a rib structure on weaving machines in successive weft insertion cycles. In each cycle a top (1), (2), (3) and a bottom weft thread (4), (5), (6) are inserted between binding warp threads (9-12) and pattern warp threads (13-16) of a series of warp thread systems so that a fabric is woven. Top (1-3) and bottom weft threads (4-6) are inwoven by a respective set of binding warp threads (9, 10), (11, 12), thereby weaving two backing fabrics. Respective pattern warp threads (13), (14); (15), (16) are interlaced in a respective backing fabric and are rib-formingly passed around over a top (2), (3) or bottom weft thread (5), (6) running between the backing fabrics which is not inwoven by binding warp threads (9-12), so that two fabrics (17), (18) with a rib structure are woven one above the other.

Abstract: A method for weaving face-to-face carpets consists of figures formed in an upper fabric and in a lower fabric. Different pile warp threads are woven-in alternately as non-working dead pile in the upper and lower fabrics to form figure-forming pile running from the upper fabric to the lower fabric and vice-versa. A double pile is woven-in with a transition in the weft direction from the figure-forming pile warp thread exiting the lower fabric to a figure-forming pile warp thread exiting the upper fabric. Carpet fabrics with face-to-face carpets separated into upper and lower fabrics is formed of different pile warp threads alternatively woven-in as non-working dead pile in the upper and lower fabrics which protrude as figure-forming pile. A color transition from one figure-forming pile warp thread to another figure-forming pile warp thread results in a woven-in double pile in the fabrics.

Abstract: A method for the face-to-face weaving of a pile fabric whereby on a weaving machine in successive insertion cycles in each case two weft threads (1), (2) are inserted almost simultaneously between binding warp threads and pile threads, so that two backing fabrics are woven, pile threads (3), (4), (5) have parts which form pile according to a two-shot weave and have other parts which are inwoven in a backing fabric, and two married pile threads (3), (4); (4), (5) perform a pile change. The successive positions (B=bottom; M=middle; T=top) of each pile thread (3), (4), (5) are predetermined in relation to the weft threads (1), (2) in a series of successive lift plans, of which every lift plan determines the positions in relation to the weft threads (1, 2) of two successive insertion cycles.

Abstract: A method for manufacturing a face-to-face pile fabric wherein first weft thread is provided in the top fabric and the bottom fabric adjacent to second and third weft threads located one above another. Three weft threads are inserted simultaneously. Each warp thread system, has binder warp threads, tension warp threads and pile-forming pile warp threads interlacing with a three-pick weave. In each case pile is formed on the first weft thread provided on the back of the second and the third weft thread. Binding of the dead pile warp thread is distributed over both the fabrics. Pile is formed on the third weft thread located on a back side. A pile thread that starts forming a pile or finishes forming a pile is first interlaced with a third weft thread before is starts forking the pile or before it is bound-in. Binder warp threads are provided to bind the first weft threads in a separate opening. Pile is formed on the first weft thread which is not provided on the back of the fabrics.

Abstract: Streakless appearing woven rugs incorporating large uninterrupted areas of a single color are formed by at least two ends of yarn of the same color alternating in the face of the rug along each of the longitudinal rows in the uninterrupted area. The two ends of yarn may alternate in an ordered or random pattern, and suitably may alternate at least every twelve inches.

Abstract: A face-to-face carpet fabric is manufactured in a one shot-weave. A face-to-face pile fabric, more particularly a one shot-weave, is woven with single rapier or double rapier with weft elimination. The imposed working repeat for the pile warp ends goes over three picks. The working repeat of the backing fabric goes over a repeat different from that number of picks, preferably over four picks.

Abstract: Method for single-spool weaving of a face-to-face fabric with bound-in dead pile which avoids color mixing at transitions from one pile thread color to another. When a color transition occurs through a pile thread bound into the bottom fabric by weft threads 1, 2, 3 and 4 before the transition (at weft thread 4) becomes active after the transition, this pile thread is successively guided to assume positions relative to the subsequent four shots 5, 6, 7 and 8 as follows: below, below, above and below, respectively. In another situation, in which the color transition occurs through a pile thread which was active before the transition (at weft thread 4) is bound in the top fabric after the transition by pile threads 5, 6, 7 and 8, this pile thread is made to assume positions relative to the previous four shots 1, 2, 3 and 4 as follows: above, below, above and above, respectively. The disclosed weaves ensure against to different colors ever occurring between two inner shots.

Abstract: A method for twin-spool manufacture of a two-shot face-to-face fabric comprising a top fabric and a bottom fabric including binder warp threads for forming the upper and lower fabrics respectively and pile warp threads bound as dead pile threads into the top fabric or into the bottom fabric for successive picks or passed as active pile threads between the top and bottom fabrics in successive picks. In successive picks there are formed alternately a shed between binder warp threads providing the top fabric and a shed between binder warp threads providing the bottom fabric with the insertion of two weft threads, one above the other, in each of said sheds. The two weft threads are taken to a height corresponding to the top fabric before insertion into the shed of the top fabric and then are taken to a lower height corresponding to the bottom fabric before insertion into the shed corresponding to the bottom fabric.

Abstract: In weaving face-to-face pile fabrics, in a 2-shot weave, pattern forming portions of pile warps go over 3 wefts while bound-in portions go over only 2 picks. Working pattern repeats--over 3 wefts--are defined for each possible pile warp by aprons which determine the positions of the pile warps. Resultant pile fabrics have precise pattern definition with no crossed piles at pattern borders.

Abstract: A Jacquard double plush fabric for subsequent division into upper and lower fabric portions includes a plurality of sheds with a single weft for each of the sheds and a U-shaped pile thread for the respective single weft, and dead thread groups woven into and distributed within the upper and the lower fabric portions, and a method and an apparatus for producing the fabric.

Abstract: A double plush weaving operation is conducted to form a two-ply material with pile yarns connecting the two plies together. Each ply comprises an outer woven layer and an inner pile-carrying layer. The two layers are tied together by warp yarns but the pile yarns are tied in only to the pile-carrying layer so that the tying-in points are not visible on the outer visible surface of the woven layer. The connecting pile yarns are cut to form two lengths of double-sided fabric with the plush side having satisfactory pile strength and the woven side having the appearance of a flat weaving machine product.
